lb all whom it may concern:

Be it known that I, AUSTIN B. HAYDEN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Im- -provement in Computing-Scales, of which the following is a specification.

My invention relates particularly to an improvement in computing-scales of the beam type, my object being to enlarge greatly the weighing and computing capacity of scales of this type and at the same time to provide a compact and economical construction. I accomplish my purpose preferably by the employment of a cylindrical computing-beam containing a revoluble computing-cylinder and in combination therewith, as a means for rotating said computing-cylinder, a longitudinally-movable poise-rod. Preferably, also, the main cylindrical beam is surmounted by a smaller supplemental casing-cylinder containing a second,computing-cylinder, the larger cylinder being graduated to one Weight denomination, as pounds, and the smaller cylinder to a lesser weight denomination, as ounces.

In the accompanying drawings,which illusl of the two casing-cylinders and their con:

tained computing-cylinders; Fig. 3, a view in front elevation of the detached cylinders; Fig. 4, a longitudinal sectional view of the cylinders; Fig. 5, a plan View of the platform and shiftable scale-pan employed; Fig. 6, an end view of the cylinders and attendant parts, showing the manner of mounting; and Fig. 7, a broken view showing a development of the surface of the larger computing-cylinder.

A represents the base or pedestal; B, the load-platform, supported on levers in the base A in the ordinary manner; C, a shifting scale- -pan mounted in a novel manner on a swinging arm C', pivoted at a point-ct at the rear of the ,central'portion of the platform B and provided at its forward end with a supporting-lug c', which rests yupon the front part of the platform when the scale-pan is in use; D D, stationary end standards resting on the base A and connected at their upper ends by a cross-piece D', (indicated by dotted lines in Fig. 1;) E, afulcrum-stand for the beam supported from said cross-piece and provided with bearings b; F, a beam-chair provided with downturned knife-edges c, engaging the bearings b, and with upturned load-hanger knife-edges hidden by cap-pieces c; G, a load-hanger provided at its ends with downturned bearings for the knife-edges at c; II, a steelyard-rod joining the load-hanger G to the levers at the baseA; I, the large casingcylinder forming the main beam and containing the large computing-cylinder I; J, the surmounting small casing-cylinder beam containing the supplemental computing-cylinder J'; K, the poise-rod for operating the large computing-cylinder; L, the poise-rod for operating the small computing-cylinder; M, an auxiliary bar-form tare-beam supported on brackets d CZ', projecting from the ends of the cylinder I and provided with a poise M; N, a scale-balancing weight, and P a beam-rack having a slot Yengaging with a pin c on the beam I and limiting the movement of said beam.

The beam I, Fig. 4, preferably is of the cylindrical form showlrto afford a housing for the computingcylinder I', being conveniently formed from a sheet ofv metal rolled to the desired shape and secured to cylinder ends ff/ by screwsfz. The poise-rod K contains the axis of the cylinder I and projects through openings at the ends of said cylinder. The rod is provided at one end with a veryhigh pitch spiral groove g, which moves over a roller g', journaled in brackets g2, projecting from one end of the cylinder. It is provided at its ends with removable hollow handles g8 and between its ends with a poise g4. These hollow handles serve to receive lead or the like in sealing the scale. The cylinder 1' is of a construction similar to the cylinder I. It is provided with ends h h', connected by rods h2. Its ends are provided with perforations for the poise-rod K, which latter is provided with a cross-rod h3, fixed securely to it and provided at its ends with perforations forming slidable connection with `the rods h2. Thus it will be seen the poiserod K is capable of longitudinal movement, and when so moved is caused to revolve, thereby. causing the computing-cylinder I IOO to revolve. A spring i serves to prevent any longitudinal play between the two concentric cylinders I and l. Thus the cylinder rotates between two fixed transverse planes and does not move longitudinally in weighing. The cylinder I is provided at its front side with a longitudinal slot Q, whose upper margin is provided with a price-index indicating in cents the price per pound. The lett-hand cylindrical column preferably is a pound-index, though, of course, in a different weight system an appropriate new unit would be selected. The cylinder I' is provided with computations indicating the cost at various prices, these computed results being arranged in circumferential columns each beneath its appropriate price-index number and in longitudinal columns each opposite its appropriate pound-index number. Thus a priceindex number heads each cylindrical column and a weight-index number appears at the left-hand end of each longitudinal column. Each horizontal column preferably contains at least two rows of numbers, the upper one containing the computations Iigured in whole cents per pound and the lower one figured in fractional cents per pound. The computation ordinarily is figured only to the halfcent per pound. The pound-index is shown with numbers from l to 50, and in Fig. 3 the cylinder I indicates twenty pounds, this being the position to which the cylinder is turned, while the poise K is moved to aposition to balance twenty pounds at the platform. Fig. 3 also shows in the price-index the price in cents per pound extending from left to right, beginning with the number 3 and ending with 50. Further illustrating the manner of arranging the computations, at the right of the ligure l of the poundindex and beneath the figure 3 ofthe priceindex occurs the computations for one pound at three and three and one-half cents per pound. In the same manner the product of any given pound-number by a given whole price-number and also its product by the next half-cent higher appear opposite that pound-number and beneath the whole pricenumber. This fact being understood, it is unnecessary to indicate half-cents in the priceindex. Further illustrating this point, opposite the iigure 50 ofthe pound-index, Fig. 7, and below ligure 4 of the priceindex in the lower row of numbers occurs the computation 225, meaning two dollars and twenty-five cents, this being the cost of iili'ty pounds at four and one-halt cents per pound. The computations are conveniently applied to the cylinder on an enameled surface supplied for the purpose.

The casing-cylinder J surxnounts the cylinder I, and it and its contained computingcylinder are quite similar to the cylinders I and I'. Here, however, a rod-like feather j serves to rotate the cylinder .Itas the poiserod L is moved, and a spring 7.: holds the poiserod irmly in contact with its roller 7c. A tierod 7a2 is shown connecting the ends of the cylinder J. The cylinder J is provided at its front side with a slot R, which is relatively wider than the slot Q. Along its lower margin is a price-index containing numbers from to 50, inclusive, these numbers representing the price per pound. The inner cylinder J is provided at its left-hand end with a circumferential column containing numbers indicating ounces, preferably from l to 32. Opposite each ounce number are placed in appropriate circumferential columns computations for the various prices, fractional prices being disregarded, because oftheirinsignicance. Eachcircumferential computation-column is graduated by short horizontal lines, each graduation indicating one cent. Thus above the ligure 9 of the price-index, Fig. 3, occurs the figure 2, and below the figure 2 a graduation-mark indicating that one is to be added to the reading 2, making the cost of seven ounces at nine cents per pound equal three cents. Fig. 3 shows a reading of twenty pounds at the large cylinder and seven ounces at the small cylinder. Thecostoftwentypoundsatseven cents per pound, for instance, is one dollar and forty cents, and at seven and one-half cents one dollar and i'fty cents. The cost of seven ounces at either of these prices is two cents, and this amount added to the cost of twenty pounds in either case gives the total cost.

It is to be observed that the scale described has a capacity of from one ounce to fifty-two pounds at a range in price of from three cents per pound to Iifty and one-half cents per pound. In addition to this the supplemental beam M has a weighing capacity of fty pounds. A machine of this capacity with numbers easily legible has a large cylinder about sixteen inches long and four and one-half inches in diameter and is readily accommodated on a counter.

The poise M may be set to balance the known weight of a jar, say, and the cylinderpoises may then be used for getting the net weight and the cost. Thus the use or" loose weights is entirely avoided.

Fig. 2 shows the cylinders I and .I provided at their right-hand ends (left-hand when Viewed from the rear) with perforations permitting weight readings from the rear, the graduations being removed through an angular distance of one hundred and eighty degrees from those in front. In Fig. 4 the poiserod K is shown provided with spirally-arranged indentations Z, which may be engaged by a pointed pin Z, projecting through a lug on the cylinder end f. These indentions correspond to the pound-graduations of the cylinder Il, and by pressing the pin Z downward a precise :reading` is assured. The beam M is shown provided at its upper margin with pound-graduations and at its lower margin with gradnations representing the price per pound when the number of pounds opposite IOO IIO

are sold for one dollar. No novelty is claimed for this method of graduation.

By means of the novel manner of mounting the scale-pan the pan can be used or pushed out of the way to clear the platform, as desired.

The knobs or handles of the poise-rods are preferably made rigid with the rods, and the operator exercises both a turning and a pushing force in moving the rods. This is not of great importance, as the feature of turning the computing-cylinder by means of a thrustingly-acting poise-rod passing through its center is believed to be broadly new and is a very important feature of the construction.

The feature of a practical construction of cylindrical computing-beam having the advantage of a greatly-increased computing capacity is of great importance, and the feature of combining a large computing-cylinder for a given weight denomination and a smaller computing-cylinder for a smaller weight denomination adds greatly to the utility of the scale. In this connection it may be remarked that the small cylinder suffices alone for Weighing and computing a large proportion of the purchases commonly'made. The feature of a circumferential pound-index and a double-row longitudinal column opposite each pound-index number made up of computations each in its appropriate circumferential column beneath the appropriate price-index number is important and is believed to be novel.

The beam improvements described are claimed Wherever applicable to a beam-scale, and the term weighing-platform in the appended claims designates any suitable support for the load connected with the beam.

No limitation is intended by the detailed description given above except as shall appear from the appended claims.

What I claim as new, and desire to secure by Letters Patent, is
